"Brooklyn Nine-Nine" has featured one of TV's most finely tuned assembles since the beginning, but it's still great fun to see the fourth season kick off with the focus solely on Andy Samberg and Andre Braugher as they attempt to get through the witness protection program together without killing each other. Whoever suggested that the former "Homicide" detective and the rascally "SNL" truant would make a sure-fire dynamic duo deserves a gold shield.

NBC's commitment to offering at least one hour of TV that's short on violence and long on tears continues with "This Is Us," a multilayered drama from the team behind "Crazy, Stupid, Love," in which families lean on each other through various hardships — and time jumps.

"Parenthood" survived — but just barely.
